Yes I know that... BUT I mean Egg Gauntlet in this incarnation... I really like it.

AND I wonder why porting HPZ would be deemed impossible??? Could it be the number of tiles/chunks... etc?
Anything to do with any objects? Or the number of them?

Or could it have to do with the level's size...

The way to access it perhaps? SBZ2 and 3 had it done where accessing a level through exiting the boundary at a certain coordinate was possible... that said, the re-release actually completely messes with the layout when you fall into the area. BUT even that can be possible in the engine to some degree...

I decided to try the 3.0.9 version now, and even though Egg Gauntlet doesn't work on it anymore (makes the engine crash or go into an infinite loop of loading), there is a new stage called Proto Palace. Yes, it seems to be a short port of the original Hidden Palace:

Oh man, I totally forgot that was in there Before the new HPZ design was started the old unfinished layout was imported as a test.

I'm surprised no-one found the cheat code for that: After enabling debug mode in the level select, play 03,03,03,0B,10,10,10,04 and select HPZ

Can you put in a similar code that switches which track is played in the new Hidden Palace? I had a nice nostalgia blast playing that level because of the music

How the hell would anyone guest that cheat code? To me it's a code that wouldn't be found without brute force.

By looking at the game data. They're all defined in Bytecode/LSelect.bin. The reason nobody found it is probably because nobody looked.
Back when the game was first released, I did look and confirmed earlier in this thread that there were no hidden codes. The code did not exist in the first release, and personally I didn't expect anything to change in subsequent updates which is why I didn't look. (And it doesn't seem like anyone else is interested in looking at these) The layout for the prototype HPZ was in the original release as HPZ Act 2, but the only way you could access it was the same as Egg Gauntlet... by modifying the RSDK file or attaching a debugger.
